My Maytag dryer works well in the Timed Dry mode but in the Auto Dry mode it runs forever and does not dry well. In the Timed Dry mode it produces plenty of heat and works fine. What is happening in the Auto Dry mode that does not make the heat properly get to a level that allows the clothes to dry like in the Timed Dry mode? I suspect it is a thermostat or some moisture sensor problem. Help appreciated!
